Built to the SIR series style, this right-hand holder accepts 16IR inserts secured by a screw-clamping mechanism. The 1-inch shank diameter and 8-inch overall length make it a practical fit for CNC lathes and manual turning centers running internal thread cycles. Minimum bore diameter is 1.16 inches, and the insert inscribed circle measures 3\/8 inches. The toolholder does not include a coolant-through port, so coolant delivery must be handled externally or by flood coolant setup at the machine.\u003c\/p\u003e\u003cp\u003eThis toolholder is intended for threading operations on internal bores in ferrous and non-ferrous workpieces across production and job-shop environments. Machinists and CNC operators running thread-turning cycles on turning centers or manual lathes will find this holder suited to standard internal threading work where bore access permits the 1.16-inch minimum bore entry. The SIR 1000 R16 style designation aids in matching to compatible inserts and existing tooling programs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRight-hand, internal threading configuration for bore thread applications\u003c\/li\u003e\n\u003cli\u003eAccepts 16IR indexable threading inserts, secured by screw clamp\u003c\/li\u003e\n\u003cli\u003e1-inch shank diameter with 8-inch overall length for rigid reach\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 1.16 inches allows threading in compact bores\u003c\/li\u003e\n\u003cli\u003eSIR series style designation for straightforward insert and program compatibility\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design keeps setup simple where flood coolant is standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 16IR series indexable threading inserts.

Power down and lock out the machine spindle before mounting or adjusting the toolholder. Confirm shank seating and clamping torque against the machine turret or toolpost manufacturer specifications. Verify insert orientation and thread direction match the programmed cycle before making a cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand of Holder\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 1.16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Inscribed Circle\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: 16IR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: SI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle Designation\u003c\/strong\u003e: SIR 1000 R16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SIR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBack of Bar to Cutting Edge\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter to Cutting Edge\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistance Across Flats\u003c\/strong\u003e: 0.905 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CARMEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100-3IN.RHHOL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":51971376677170,"sku":"100-3IN.RHHOL","price":251.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c0fb717c88dd4ce7af8d07d3df05425.jpg?v=1789956233","url":"https:\/\/voomisupply.com\/products\/carmex-100-3in-rhhol-threading-toolholder-1-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
